To all whom it may conce-m.

Be it known that I, HEARD Rnsrnss, a citizen of the United States, andresident of the borough of Manhattan, city of New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in ventilators, of which the followin is a specification.

This invention re ates to ventilators.' The object of the invention isthe production of an'adjustable ventilator, that can be locatedand'secured in place in window frames or other openings of variouswidths. A. second object is to rovide a ventilator, through f) air canbe obtained, but which prevent rain, sleet, snow, insects and the liketo pass therethrough.

The organization of the invention comprises a plate with openings thatare4 protected by hoods. A screen is secured to the inner face of theplate and covers the openings therein. Extension members are slidablyconnected to the plate of the ventilator, to enable it to be connectedto window frames or other openings-of various widths.

The accompanying drawings exemplify one form of the invention and inwhich Fig..

1 represents an inside elevation of a window frame, with the improvedventilator connected'thereto, both having portions. thereof broken away;Fig. 2 shows an outside elevation of the ventilator; Fig. 3 indicates asection of Fig. 1 on the line 3, 3; Fig. 4 is a section of Fig. 1 on theline 4, 4; Fig.v 5

indicates an enlarged fragmentary portion of Fig. 4; and 6 shows anenlarged fragmentary portion of Fig. 3.

A fragmentary portion of a window frame is indicated with the sidemembers 20, the horizontal member 21, and the sash 22.

The ventilator com rises the outer reetangular plate 25, whic has guardsstamped therefrom bulging outwardly formingthe ventilating o nings 26with the protecting hoods 27.` e roofs of the latter are curved at theirsides 28 and at their front portions 29. An opening 30 is indicated atthe bottom of each hood. The openings 26 are in parallel rows, with theopenings of one row above the corresponding openings of the other row.The openings of one row may, however, break joints with the openings ofthe next adjacent row. The said openings are preferably made by pressingy ing flanges.

out the material of the .plate 25, the hoods resulting from the processof manufacture.

A horizontal U-shaped inwardly extend-` ing upper normally horizontalflange 35 and a similar U-shaped inwardly extending lower normallhorizontal flange 36 are formed with t e plate 25 to providehold- At theopposite ends of the plate 25 are formed the similar inwardly extendingU-shaped fianges 37 and 38..

A fiy screen 40 is encased by a frame having at its upper and loweredges respectively the similar U.shaped fianges 41 and at its ends bythe similar Uv-shaped flanges 43. The screen 40 is adiacent to the innerface of the plate 25 and covers the openings 26.

The flanges 41 bear against the inner face of the plate 25 andtheflanges 43 are encased by the fianges 37 and 38.

On the opposite ends of the plate 25 are shown the similar extensionmembers or end pieces 45. Each of the members 45 has formed therewiththe curved cut-out portion 47, the upper flange 48, the similar lowerfiange l49 and the -side U shaped end flanges 50 with the openings 51.Angle shaped adjusting anges extend from the members 45. The saidmembers 45 are slidable and spaced from the fiy screen 4() to preventthem contacting therewith, The flange 48 engages the flange 35 and theflange 49 engages the flange 36.

To use the ventilator it is located in a window frame or other openingand if 1u the former above or below a sash thereof.

The extension members 45 are located with their end flanges 50 bearingagainst the adjacent Side membersof the window frame arranged upon theinner side of the plate and carrying a ily screen, said frame having itsends held within the holding flanges, guide flanges formed integral withthe top and bottom ofthe plate, and end pieces having slidableengagement with said guide Hanges and being adjustable longitudinally ofsaid plate, said end pieces being spaced from the fly screen by the in-IU wardly bent portions of the holding flanges which serve to keep theend pieces from contacting with the fly screen and thereby protect saidily screen from being scraped when the end pieces are bein adjusted.

Signed at the borough of of New York, in the county of New Yorc andState of New York this 9th day of March A. D. 1922.
